| 1204 To Rm.{William Robotham - Chief Engineer} 5.6.39. We have an old 25/30 engine (originally in Sg{Arthur F. Sidgreaves - MD}'s car) now at Shardlow. This is our most obsolete engine that is in reasonable condition and is not likely ever to be wanted. It is one of the old 20/25 mocked up with 3.5 bore block. Would give between 50 and 60 H.P. at 1500 R.P.M. but it would be necessary for them to fix up a governor. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} | ||
